Percutaneous vascular plug for incomplete surgical left atrial appendage closure.
Surgical left atrial appendage (LAA) exclusion has a failure rate as high as 60% due to persistent residual flow in the LAA or large LAA remnants. We describe a novel technique for treatment of incomplete surgical LAA ligation, and define the mechanism that led to persistence of the remnant LAA without any thrombus formation.
متن کاملCONGENITAL PARTIAL PERICARDIAL DEFECT WITH HERNIATION OF THE LEFT ATRIAL APPENDAGE
Congenital defects of the pericardium are considered rare. Until 1979 , the reported cases were only about 200.1 Total absence of the left pericardium is the most common defect2 and less common is a partial defect of the left pericardium. Other types, i.e. isolated right-sided defects, total pericardial absence and diaphragmatic pericardial defects are very rare.3 Before the last decade, t...
متن کاملA Semi-Automated Algorithm for Segmentation of the Left Atrial Appendage Landing Zone: Application in Left Atrial Appendage Occlusion Procedures
Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...
متن کاملSurgical left atrial appendage ligation is frequently incomplete: a transesophageal echocardiograhic study.
OBJECTIVES This study sought to determine the incidence of incomplete ligation of the left atrial appendage (LAA) during mitral valve surgery. BACKGROUND Ligation of the LAA to prevent future thromboembolic events is commonly performed during mitral surgery. However, success in completely excluding the appendage from the circulation has never been systematically assessed. METHODS Using tran...
متن کاملThe Left Atrial Appendage Revised
Nonvalvular atrial fibrillation is associated with a 4- to 5-fold strokes increase and may be responsible for 15% to 20% of all strokes in the elderly. In this scenario, the left atrial appendage thrombus would be the associated with 90% of cases. The use of anticoagulants, percutaneous devices, and the left atrial appendage surgical exclusion is still an open discussion. For left atrial append...
متن کاملAdvances in surgical treatment of atrial fibrillation.
Atrial fibrillation (AF) is the most common sustained arrhythmia. It is associated with increased risks of death and stroke; most strokes in AF patients are thought to arise from thrombi in the left atrial appendage. Surgical ablation of AF includes excision of the left atrial appendage and is an effective means of treating this arrhythmia, with the classic Maze procedure curing AF in >90% of p...
